Patent number: 9815469Abstract: A vehicle control device calculates a target line pressure based on an instructed torque capacity of a friction engaging element and a belt capacity when the friction engaging element is determined as not engaging. Belt capacity is calculated using an input torque of a continuously variable transmission mechanism. The device calculates torque down in a driving source based on an upper limit line pressure when the calculated target line pressure exceeds such line pressure. A limit torque capacity of the friction engaging element is calculated using the input torque and a belt capacity when the friction engaging element is determined as not engaging. The belt capacity is calculated using an actual line pressure. The device restrains a slip between pulleys and a power transmitting member using the target line pressure, the torque down, and the limit torque capacity when the friction engaging element is determined as not engaging.Type: GrantFiled: February 25, 2015Date of Patent: November 14, 2017Assignee: JATCO LtdInventors: Kunihiro Takahashi, Yoshinobu Kawamoto, Hideshi Wakayama
